This is the newly authorized Organizational Flag for Garrison Support Units of the Army Reserve. The GSU performs the same kind of housekeeping and support functions for the USAR as the U.S. Army Garrison does for the active side of the house. Accordingly, it has the same pattern of organizational flag--teal blue field with yellow fringe and the insignia for "branch immaterial" between two arcs inscribed with the unit designation.Tom Gregg, 12 September 1999
